workup.ADDITIONan immobilized catalyst with immobilized cells containing aspartase

实验过程

Still alternatively, both an immobilized biocatalyst with immobilized cells containing maleate isomerase and an immobilized catalyst with immobilized cells containing aspartase are combined and packed into a column and an aqueous solution of maleic acid and ammonia or an aqueous solution of ammonium maleate is passed through the column, to produce L-aspartic acid by a single-step process from maleic acid.
